Credentials & Testimonials


Choosing a watchmaker can be a confusing process for many collectors, as it can be difficult to judge a watchmaker's competence and ability. When choosing a doctor, auto mechanic, or accountant, you always look for an MD, ASE Certification, or a CPA, in combination with a solid reputation. You should do the same for your watchmaker to assure that you are getting top-notch professional service.

There are only a few professional certifications that a watchmaker can get in the United States. These are available through the American Watchmakers-Clockmakers Institute (AWCI) in Harrison, Ohio. The two certifications that apply to mechanical watch repair are Certified Watchmaker (CW) and Certified Master Watchmaker (CMW), with the CMW being the more difficult of the two. There is an extensive testing process which needs to be completed successfully before acquiring either one of these certifications. The test includes a 600 question written examination, the repair of two wristwatches, and the manufacture of 2 watch parts to a very high standard. My testing procedure took about 3 months in total. In 1999 (when I took my exam), only 2 watchmakers in the entire United States earned status as a CMW.

The group of genuinely certified watchmakers is very small, and sometimes people use similar sounding (but not genuine) terminology in their advertisements. Take, for example, someone who claims to be a "Master Watchmaker". It sounds official, but it is merely a self-appointed title. There is no official body in the US which grants such a title, and to an educated consumer it should be meaningless. To help clarify such problems, the American Watchmaker's Institute recommends a specific notation for one's certifications, such as Certified Master Watchmaker, AWCI. For more information on the certification process, see the AWCI's web site at

I also have a Bachelor's Degree in Mechanical Engineering, which demonstrates an understanding of mechanics, mathematics, theory, and excellent problem-solving skills.

I am also a published author in various newsletters and magazines. I have written for International Wristwatch Magazine. One or more of these articles is available on my web site, under the 'recently published articles' page.  I have also contributed to Bruce Shawkey's Vintage Wrist Watch Report, the newsletter of the Society of Military Horologists, the newsletter of the International Watch & Jewelry Guild, and the Horological Times, a publication of the American Watchmaker's-Clockmaker's Institute.
